SPECIFICATION forming part of Letters Patent No. 445,962, dated February 3, 1891.

Application led October 14, 1890. Serial No, 368,115. (No model.)

To @ZZ whomj it may concern: 13, in which works a piston 14, which is of o 13e it known that I, J AMES P. MONTGOMERY, considerablelength as compared with the casa citizen of the United States, residing at South ing. The latter is practically provided with Pueblo, in the county of Pueblo and State of a horizontal partition or diaphragm 15, from. 5 Colorado, have invented a new and useful which the wall or web e depends and in which Pump, of which the following is a speciiicathe bore 13 is formed. The partition or dia- 55 tion. phragm 15 on the opposite side is provided This invention relates to pumps; and it has with an opening 16, the upper end of which for its object to construct a force-pum p which forms a seat for the check-valve 17.

This rod may either be made of some mate- Like numerals of reference indicate like -rial-such aswood-thatislighter thanwater, 75 parts in all the iigures. or it may, as shown in the drawings hereto 1 designates the pump-casing, which is proannexed, beniade of tubing, which must be vided with a central chamber 2, into which of such dimensions and construction as to be opens the induction-chambers 3 3, one on capable of floating in water. This pump-rod each side. The induction-chambers are sepais carefully constructed with relation to the 8o rated by a central wall or web 4. The upper column of water which, during operation, is ends of the induction-chambers are interiorly contained in the exit-pipe, so as to support screw-threaded, as shown at 5, to receive the the weight of the piston or plunger. It folplugs G, having the inlet-openings 7 at their lows that on the upstroke of said plunger the upper ends. At the lower ends of the inletoperation will be exceedingly easy, the plun- 85 openings 7 are formed seats S for the floating ger being assisted in the upward direction ball-valves 9. The lower ends of the plugs 6 by the floating tendency of the plunger-rod, are provided with perforations 10 to receive while on the downstroke the entire force of pins 11, by means of which the valves 9 are the operator or the motive power may be exretained in the cages or valve chambers pended upon forcing the water upwardly 9o formed bythe plugs (5. The said plugs may, through the exit-pipe. as will be observed, be very readily removed The operation and advantages of my i1n when itis desired to have access to the valves proved pump will be readily understood from contained therein, the upper ends of said the foregoing description, taken in connec plugs being provided with wrench-seats 12. tion with the drawings hereto annexed. On 9 5 In the chamber 2 of the casing 1, between the upstrole of the piston or plunger the one side of said casing and the wall or web valves 9 will be open and water be admitted 4. in the latter, is formed a cylindrical bore through the induction-chambers into the chamber 2 of the casing below the horizontalV partition 15. The valve 17 is meanwhile supported upon its seat 16. On the downstroke of the plunger the valves 9 will be forced to their seats and the contents of the chamber 2 below the partition l5 will be forced upwardly past the check-valve 17 and into the exitpipe.

My improved pump, as will be seen from the foregoing description, is very simple in construction, and it may be manufactured at a moderate expense, the entire device comprising but a single casting, namely, the casing 1, three plugs, three valves, and the induction-pipe. Owing to this simplicity of construction,the device is not liable to get out of order, and in case of derangement of any of its parts they may be Aeasily reached for repairs.

I prefer to provide the inlet-openings 7 of the plugs (3 with screens, for the purpose of preventing the ad mission of obstructions into the pump. I also reserve therightto provide the upper end of the bore 13 with a packingbox such as shown in dotted lines at 26, although this is usually deemed unnecessary.

Having thus described my invention, I claim and desire to secure by Letters Patent of the United Statesl. In a pump, the casing having a chamber provided with a horizontal partition having a downwardly-extending web or wall, the induction-chambers opening into said chamber belo7 saidpartition and having plugs provided with iioating valves, the cylindrical bore formed in the horizontal partition on one side of the central web, an opening formed in the opposite side of said partition and having an upwardly-opening check-valve, and the exit-pipe extending upwardly from the top of the casing, substantially as set forth.

2. In a pump, the casing having alhorizontal partition provided with a cylindrical bore and an openinghaving a seat at its upper end for a check-valve, the induction-chamber opening into said casing below the horizontal partition and provided at their upper ends with screwthreaded plugs having inlet-openings and float-valves closing the latter, the piston or plunger mounted in the cylindrical bore, having the upwardly-extending pump-rod made of tubular or lioating material, and the exitpipe extending upwardly from the top of the casing above the cylindrical bore in the horizontal partition in the latter, substantially as set forth.

3. In a force-puni p, the herein-described casing, having a horizontal partition provided with a cylindrical bore and with an opening having a valve-seat at its upper end, a checkvalve mounted on said seat, an opening in the top of the casing above said check-valve having a plug, a transverse rib formed upon the upper side of the horizontal partition, the induction-chamber opening into the casing below the horizont-al partition and having the iioating valves at the upper ends of their inletopenings,the exit-pipe extending upwardly from the top ot' the casing above the cylindrical bore, the piston or plunger working in the latter, and the plunger-rod'extending upwardly through the exit-pipe, said plungerrod being made tubular or of iioating inaterial, substantially as set forth.

In testimony that I claim the foregoing as my own I have hereto affixed my signature in presence of two witnesses.

J. P. MON'GOMERY.
